Backblaze is an online backup company. In light of jokes making the rounds alluding to the idea that backup services are now unnecessary considering the National Security Agency already has a copy of everyone’s data, one of Backblaze’s employees decided to put that theory to the test.

According to CNET, Backblaze’s Yev Pusin sent a Freedom of Information Act request to the NSA in June asking “for a copy of all the agency’s data relating to himself.”

Perhaps unsurprisingly, the NSA denied Pusin’s request, citing matters of national security; the NSA wouldn’t even acknowledge “the existence or non-existence” of such data, according to its letter back to Pusin.
